You cant fly without a cockpit. There is the 2D and 3D cockpits. You should check out PMC Tactical Forum Seifer's cockpit editor topic. More to come to this page later.

2D Cockpit is the gif graphics file format made cockpit which you can change views only in certain directions.

3D Cockpit is the 3d model cockpit which you can view in any direction, especially with TrackIR this is very cool.
